Abstract Ionised gas, i.e., plasma, is a medium where electrons-ions dynamics are electrically and magnetically altered. Electric and magnetic fields can modify plasma’s optical loss, refraction, and gain. Still, plasma’s low pressure and large e

A Fabry-Perot microcavity-based accelerometer was tested in an anechoic chamber to measure the limiting noise for the device operating in air at room temperature. The acoustic response illustrates the design requirement for an optical microphone.
